Description

Technical Field

[0001] This utility model relates to the field of PVC pipe production technology, specifically to a traction machine for PVC pipe production with a correction function. Background Technology

[0002] In the pipe production process, the pipe needs to be extruded and shaped using an extruder. After the pipe is extruded from the extruder, it goes through cooling, shaping, and cutting processes to complete the entire pipe production process.

[0003] In existing pipe production, after the pipe is extruded from the extruder, due to the long production line, a traction machine is needed to ensure the pipe moves continuously forward. This ensures the pipe is stably pulled backward under force. Furthermore, aligning the pipe with the internal traction track of the traction machine is often inconvenient. Therefore, we propose a traction machine for PVC pipe production with a correction function. Utility Model Content

[0004] To address the shortcomings of existing traction machines in aligning pipes with the internal traction tracks, this invention provides a traction machine for PVC pipe production with a correction function. It has the advantages of real-time monitoring of the pressure through a pressure sensor and correction of pipes through the telescopic sliding of a support plate, thus solving the problems mentioned in the background art.

[0005] The technical solution of this utility model is implemented as follows: A traction machine for PVC pipe production with a correction function includes a processing table, a traction mechanism set on the top of the processing table, and one side of the processing table and the operating table connected. Multiple guide rollers are rotatably connected to the top of the operating table. U-shaped frames with downward openings are symmetrically connected to the top of the operating table. The guide rollers are rotatably connected to the U-shaped frames through rotating shafts. Pressure blocks are slidably connected inside the U-shaped frames, and one side of the pressure blocks is fixedly connected to the rotating shaft on the guide rollers. Both sides of the pressure blocks are connected to a pressure testing mechanism. A mounting frame is fastened to the end of the operating table. Arc-shaped plates are symmetrically arranged inside the mounting frame, and the arc-shaped plates are connected to the side wall of the mounting frame through a telescopic mechanism. It also includes a control box, in which a controller is set, and the traction mechanism, pressure testing mechanism, and telescopic mechanism are all connected to the controller.

[0006] Optionally, the pressure testing mechanism includes a guide rod vertically connected between the U-shaped frame and the operating table, the guide rod passing through the pressure block and having a first spring connected to both sides of the pressure block; The end of the first spring is tightly fitted with an annular support. The annular support and the first spring are coaxially arranged with the guide rod. Both ends of the guide rod are coaxially connected to a support base. A pressure sensor is connected to the support base. The annular support and the pressure sensor are in contact.

[0007] Optionally, the telescopic mechanism includes an electric push rod connected to the side wall of the mounting bracket, with a support plate tightly fastened to the telescopic end of the electric push rod, and the arc plate and the support plate being slidably connected.

[0008] Optionally, a plurality of crossbars penetrating the support plate are fastened to one side of the arc-shaped plate, and a limiting end plate is coaxially connected to the end of the crossbars. A second spring coaxial with the crossbars is fastened between the limiting end plate and the support plate.

[0009] Optionally, the electric actuator can be connected via a mounting base and the side wall of the mounting bracket.

[0010] Optionally, the traction mechanism includes a mounting bracket connected to the top of the processing table, on which symmetrically arranged conveyor belts driven by a drive motor are mounted.

[0011] Compared with the prior art, this utility model can monitor the pressure in real time by using a pressure sensor based on the different forces exerted on the two ends of the guide roller when the pipe is deviated. Furthermore, the support plate can be controlled to slide and extend by an electric push rod. The reciprocating sliding adjustment can restore the pipe to its initial position. This utility model not only has a simple structure but also greatly improves the practicality of the device, effectively corrects the deviation of the pipe in a timely manner, and ensures the production quality of the pipe.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Reference Figures 1 to 4 This utility model provides a technical solution: a traction machine for PVC pipe production with a correction function, including a processing table 1, and a traction mechanism is provided on the top of the processing table 1. The traction mechanism includes a mounting bracket 20 connected to the top of the processing table 1, and a conveyor belt 21 driven by a drive motor 22 is symmetrically arranged on the mounting bracket 20.

[0020] like Figure 1 As shown, the processing table 1 and the operating table 3 are connected on one side. Multiple guide rollers 2 are rotatably connected to the top of the operating table 3. U-shaped frames 11 with downward openings are symmetrically connected to the top of the operating table 3. The guide rollers 2 are rotatably connected to the U-shaped frame 11 through a rotating shaft. A pressure block 4 is slidably connected inside the U-shaped frame 11, and one side of the pressure block 4 is fixedly connected to the rotating shaft on the guide roller 2.

[0021] In actual use, the two sides of the pressure block 4 are connected to the pressure testing mechanism. The pressure testing mechanism includes a guide rod 16 vertically connected between the U-shaped frame 11 and the operating table 3. The guide rod 16 passes through the pressure block 4 and is connected to a first spring 12 on both sides of the pressure block 4. The end of the first spring 12 is tightly fitted with an annular support 13. The annular support 13, the first spring 12 and the guide rod 16 are coaxially arranged. Both ends of the guide rod 16 are coaxially connected to a support base 14. A pressure sensor 15 is connected to the support base 14. The annular support 13 and the pressure sensor 15 are in contact.

[0022] like Figure 3 As shown, when the tube located at the top of guide roller 2 ( Figure 1When the deviation occurs (as indicated by the middle arrow A), the forces acting on the two ends of the guide roller 2 are different, resulting in different pressures on the pressure sensor 15 at the ends of the guide roller 2. Therefore, the deviation of the pipe can be monitored based on the real-time monitoring of the pressure sensor 15.

[0023] In summary, when this PVC pipe production traction machine with a deviation correction function performs deviation correction, such as... Figure 2 , 4 As shown, a mounting frame 8 is fixedly attached to the end of the operating table 3. An arc-shaped plate 10 is symmetrically arranged inside the mounting frame 8. The arc-shaped plate 10 is connected to the side wall of the mounting frame 8 through a telescopic mechanism. The telescopic mechanism includes an electric push rod 5 connected to the side wall of the mounting frame 8. A support plate 9 is fixedly attached to the telescopic end of the electric push rod 5. The arc-shaped plate 10 and the support plate 9 are slidably connected. Multiple crossbars 18 penetrating the support plate 9 are fixedly attached to one side of the arc-shaped plate 10. A limiting end plate 6 is coaxially connected to the end of the crossbar 18. A second spring 19 coaxial with the crossbar 18 is fixedly attached between the limiting end plate 6 and the support plate 9. The electric push rod 5 is connected to the side wall of the mounting frame 8 through the mounting base 17.

[0024] When the pressure sensor 15 detects that the pressure on both sides of the guide roller 2 exceeds the set value, the electric push rod 5 controls the support plate 9 to extend and slide. By repeatedly sliding and adjusting, the pipe can be restored to its initial position. A second spring 19 is provided between the support plate 9 and the arc plate 10, which can protect the surface of the pipe. This utility model also includes a control box 7, which contains a controller. The pressure sensor 15, the drive motor 22 and the electric push rod 5 are all connected to the controller.
